Asthma is a chronic respiratory condition that respects no age though it is particularly prevalent amongst young children. The general symptoms are coughing, wheezing, shortness of breath and tightness in the chest.

This is caused because the airways of the patient are blocked. The blockage is caused due to surrounding muscles cramping the airways, a swelling of the lining of the air passages and a lining of excessively produced mucus.

Asthma was identified by Hippocrates, the Greek pioneer of medicine, and has been known since about 460 BC. However, the precise causes are still not known, nor has a cure for the condition been found. Nonetheless, the following are considered to be the causes of asthma:

* A person is more likely to develop an asthmatic condition if there is a family history of asthma or allergies.

* Quite possibly this family history with certain environmental factors play a role whether or not the person develops asthma.

* In the last few decades, the rise in asthma could be attributed to modern lifestyle changes such as changes in diet and housing and a more hygienic environment.

* Smoking during pregnancy is a significant risk factor in a child developing asthma at a later stage.

* Children of smokers are more susceptible to the condition.

* Adults can develop asthma after a viral infection.

* Irritants in the work place can be a causative agent.

* Atmospheric pollutants are a significant trigger.

* Extremes in temperature, dryness and humidity are causative agents.
